Greetings,

Here is a screen shot of the packaged unit at Ten Tec.? Please comment on the button labeling and if this will be sufficient.? Does anything else need printed on the front cover?? This is a graphic overlay over a bone ivory painted clam shell aluminum case.? Pneumatic and power connections are on the back side of the case.

Questions:?
1)? Do we need an emergency stop switch?? I have incorporated one. Should I remove it?
2)? Is an aluminum metal case acceptable?? Or does it need to be fiberglass /? plastic?? Does it need to be waterproof, IP-65, etc?
Aluminum cases are cheap, rapidly manufactured and can be made TODAY. If we go with an existing plastic or fiberglass case that will need to be machined which is slow and costly.? I'm looking for solutions that we can bang out a hundred or a thousand a day with.? I doubt that I will manufacture that many but I am approaching this froma manufacturing point of view, like an appliance or appliance control.? The key word here is VOLUME. That is how we win this thing.


 

typically with ventilators "emergency start" is more important than emergency stop!

In event of failure it will be more important to disconnect the ventilator and connect it to an alternative, such a ambubag.

Having "alarm pause" (typically suspending alarm for a minute or two) is probably the more important a button to have.

The sensory overload when things go wrong and you're trying to figure out which of 20-30 possibilities you are dealing with in a matter of minutes, with every alarm blaring at you, is not to be underestimated!

I agree with Erich, I can't think of a situation where I'd need to shut off a vent emergently. In the ICU we keep an ambu bag? in the room at all times. If there's an emergency, I just unhook the vent tubing from the patient and use the bag until I identify? / fix the problem.?

I also like the idea of an alarm pause, exactly as Erich says, alarm fatigue is real.
I'm new to this project, is there any sort of visible alert for alarms ie a flashing light. If not, this might be a good idea. There are many devices that could alarm in a patient room and it can be hard to determine which is which. This is particularity important in COVID where many hospitals are pulling staff from other fields or even other geographies who may not be familiar with what machine makes what sound. Additionally, with all the PPE requirements and negative airflow rooms, it can be hard to hear/locate sounds.

As for materials, standard vent cleaning protocols are to wipe the exterior with a sani-cloth (usually purple or orange top). The case will need to withstand wiping with a dripping wet cloth containing isopropanol, bleach,?Alkyl C12-18 Dimethyl benzyl Ammonium chloride, and?Alkyl C12-18 Dimethyl Ethylbenzyl Ammonium chloride. So mild waterproofing and chemical proofing will be needed. I can't say for sure, but I'm fairly certain that aluminum with silicone sealed joints would be fine.
